Circuit boards have been in the market since the World War days. It is used in many electric pieces of equipment and contraptions to hold electric parts such as electronic transistors, Light emitting diodes, electrical fuses, and other. Using conductive pathways or tracks, it connects various electronic computer peripherals to perform specific roles, just like in wireless to get radio signals using different absolute frequencies and later change over it to sound waves to which multitudes may hear. Almost all commercially made electronic devices have printed circuit boards (PCB) in them.
